Serial No. 254,648.

State of Ohio, have lnvented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers and is shown more particularly as relating to the type of machine in which there are a series of manipulative setting levers and an operating mechanism and has among its objects to provide improved locking and alining devices in connection therewith; this application being a division of a (to-pending application Serial No. 160,416, filed by me on June 6, 1903.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 represents a detail view of the locking device for the op erating mechanism; and Fig. 2 represents a detail sectionalized view showing the alining devices and also the locking device referred to in Fig. 1.

In this particular machine there are a series, of manipulative levers which are adjusted to different positions according to the amount to be registered or recorded and then the completion of the operation is effected by the. rotation of a main operating shaft by means of a crank handle or other suitable means. The aforesaid setting levers 21 are each fast to disks 25 which are journaled upon a transverse shaft 21", and these disks 25 are formed with gear teeth meshing with corresponding teeth of vertical rack bars 27 which are adjusted to various heights according to the movements of the setting levers and thdreby the differential movements of these vertical rack bars may be utilized to effect the registration or recording of the various amounts, all of which will not be further described as it constitutes no part of the present invention. "Subsequent to the setting of said levers, the completion of the operation of the machine is effected a rotation of the main operating shaft 2d which is rotated through the medium of any suitable crank handle or other power application means, the direction of rotation of this shaft being shown by the arrow in Figs. 1 and 2 and the shaft in-this particular instance being adapted to have one complete revolution at each operation of the machine.

In order to aline the setting levers so that they will always stop at a point directly opposite some numeral upon the index plates, and for the further purpose of locking the setting levers and the parts controlled thereby, during the revolution of the crankhandle, I provide a series of locking and alining pawls 80, best shown in Fig. 2, and pivotally mounted upon the transverse shaft 73. These pawls are of hell crank formation and the forward end of each is formed into a wedge-shaped upturned nose 81 which cooperates with the teeth of its respective locking plate 25 fast on the side of the disk 25. The downwardly turned rear ends of these awls extend in front of the cross bar of ocking frame 85 which is ivotally mounted u on the shaft The frame 85 is provide with a series of set screws 86 which cooperate with noses 80 on the pawls SOfor adjusting the relative positions of the two parts. Coil springs 85 are mounted upon the set screws 86 and the noses 80 of the pawls to normally hold the two separated. The locking frame 85 is-formed with an arm 87 whichis provided with an anti- .friction roller 88. This roller operates in the cam groove 89 of a box cam 89. which is secured upon the rotary shaft 24:. The formation of the cam groove 89 is such that when the parts are in their normal positions, shown in Fig. 2, the pawls 80 may be rocked downward by disks 25 together wth thelevers 21. After the levers have been set however,- and the rotation shaft moved from its normal posiforward until the set screws or bolts 86 engage'the noses 80', when the pawls 80 become locked against movement thereby also looking the adjusting levers 21.

After the registration has been made and l the printing accomplished the pawls 80 are the operation of the respective tion', the frame 85 is cammed downward and released and allowed to drop by the frame 85 rotking back to a position in which all ten-' sion upon the springs 86 is removed. During the time theframe 85 remains in this position, the levers 21 are virtually free,: 1d are returned to their normal posltions'by evices -hereinafter described. After the levers 21 have been so returned the fra1ne85 is again rocked forward into the position shown in Fig. 2, whereby the, springs 85.- are put under tension to cause-the pawls '80 to properly aline and restrain the levers 21 when they are subsequently operated. When any one of the levers 21 is actuated and while it is in a position intermediate any two characters on the index plates the nose 80 will be contacting with the end of its re spective screw bolt 86, and if an attempt be made to operate the machine at this time, the initial downward movement of the frame 85 will force the alining pawls to become seated between the teeth on the plates25,

and will thus'move the levers 21 to position-s in alinemcnt with either one numeral or the other and lock them so. If any one of the levers 21 is held in an intermediate position friction rollers 17 2, whi'ch'when the frame is rocked, engage the respective levers 21. and force them forward. Each of the levers 170 is formed with a nose 173,0arrying an antifriction roller 174 which cooperates with a cam 17 5. These cams are mounted upon the rotation shaft 24 and'ar'e so formed 'as to force the levers 170 forward after the registration and v printing. have taken place. hen a lever is operated the bar 171 is only forced backward a distance equal to the movement of said lever.

Each of the disks 25 is formed with a notch 177 throughwhich projects a tie bar 178 connecting two pivoted levers 179, which are fastio a sleeve 179 journaled upon a transverse shaft 180,.as shown in Figs. 1 and 2. The tie bar 177 is provided ,with a series of antifriction rollers 181' which relieve the friction incidental to the .contactofthe walls of the'notches lTT; in forcing c tie bar rearward; One of, illfilev-Qrfi 1ltQiSi I d 1 at its lower end with .,-11 0Ql;;l;8 2,,wl1ich normally stands in the path of a'pin 183 mounted upon the box. cam-Z1, aBy this means the operating crankihandle locked .vwhen; all

the lovers 21' are inutheirnormalpositions. v

Should one'of thcselevers however be moved, lock said alinlng and looking devices. and 130 I from its normal position, the levers 179 will the scope ofthe claims which follow.
